Optical Isolators

Tunable free-space optical isolators

Our high-performance optical isolators are designed with industry-leading performance to protect laser systems from damage and feedback. Perfectly suited for quantum technologies, designed for perfect integration into TOPTICA lasers.

Whether you need to enhance the stability of TOPTICA’s narrow linewidth, long coherence length lasers or protect Watt-class lasers and amplifiers from damaging back reflections, trust in TOPTICA's reliable single-stage (>35 dB) and double-stage (>60 dB) optical isolators.

  • Designed and manufactured by the laser experts of TOPTICA
  • All Wavelengths with the best performance, highest transmission & extinction from the UV to NIR, 360 nm to >1750 nm
  • All internal components angled to eliminate back reflection
  • Custom wavelengths and form factors available

The same high-quality isolators that make TOPTICA lasers the industry standard are now offered individually. Custom and private-label isolator inquiries are welcome.

Your Benefits

Best guardian of your laser performance
Protect your laser from destabilizing external influences that can cause noise or damage with industry-leading isolation
High transmission without sacrificing protection
Our isolators feature high transmission so every forward photon counts. 
Wide wavelength coverage
Our wavelength-tunable isolators are specified across the whole tuning range to give you the flexibility to dial in your tunable diode laser frequency without worrying if your isolator can handle it. 
High power handling
Our isolators are constructed to handle more than enough power for your application.

Applications

Proprietary resonator design, that is solid, adjustable with closed resonator and air sealed
Eliminate feedback-induced damage
Eliminate feedback to maximize ECDL stability
Reduce back reflections from fiber coupling
Stabilize injection locking

Options

Custom and OEM isolators are available upon request
Our team of expert engineers can tackle the most demanding applications. Please contact us to configure custom isolators special for your needs.
Single-stage isolation
Single stage devices provide guaranteed >35 dB isolation and >85% transmission over individual wavelength ranges spanning the UV, visible, and NIR, with center design wavelengths from 370 to 1350 nm.
Dual-stage isolation
Dual stage isolators provide guaranteed >60 dB isolation and >80 % transmission over individual wavelength ranges spanning the visible and NIR, with center design wavelengths from 660 to 1070 nm.
Compact single-stage isolation
TOPTICA’s miniature optical isolators reliably provide high transmission and isolation but in a small form factor (< 1 cm³). This reduced size allows many lasers and isolators to be integrated into small systems.
Extended wavelengths isolation
TOPTICA offers additional isolators in the UV, visible, and NIR, with center design wavelengths between 390 and 2300 nm for single-stage isolation, and between 405 and 1585 nm for dual-stage isolation.
